I recently did an Arri 416 shoot with my Cine Live rig. I tried powering the camera from the sled with Media Blackout's Alexa power cable. It powered the camera but was showing a ground warning and we immediately pulled the plug to avoid bad things to happen and went on with the on board battery. The camera owner said that it has to do with the video tap (SD) creating a ground loop. Is that normal? Is there a way to power this camera through the sled or do I have to keep on with the on board battery?
Thanks and fly safe.
